Y `such operations as the 'l makingof tongues lit closely together.

and grooves on the edges of wood flooring,

it is necessary 'that the width of the tongues and grooves shallbe accurately adjusted to It has beenound diiiiculty ltokeepl the cutters in such shape that'the tongues and grooves will exactly coincide.y It' the cutters become dull, the

tongues will-be thickened andthe grooves will be narrowed, resulting in too close afit.

It is alsofound that Ithe condition of the wood, whether hard or soft, moist or dry,

also changes the width ofthe tongue' or groove which a lgiven cutter l,will produce.y

t is the-objectfof mypresent invention to provide meansA by which a molding cutter may be easily and quickly adjust-ed to bring the width of the tongue or-groove to an eX-y L actfdesired dimension. n Y

In the accomplishment ofA this object I1 provide means for adjusting one ormore of the molding cutters axially of the cutter'V head so that these cutters may bepositioned slightly'` out' of.'V alignment rwith thev other' cuttersr tto increasethepwidth ofzthegroovm or to .decrease the: width ot-the tongue'jfpro-,L

` i i. 'tllejSlide to. be .drawn tightly together t() duced thereby.

l, have also pro-vided novel ,andV e'ectivef means for securing the cutterinits adjusted` position and' for holdingit iirmly from dis# placement. f

My invention further relates to arrange-- ments and combinations of parts which Awill be hereinafter described' and more particu-4 larly pointed out in theappended claims.

A .preferred form of the invention"V is shown in the drawings in which p .f

' taken along theirregular line 2,2 in Fig. 1';

The outer. portions of the'h'ead10` and ring 11 are cut away to proportions 14.

Guide-ways Vportion18ct' thehead 1()k which is also pro-.7

vided with an axial opening v19 to receivel a drlvinglspindle. a v i l' inventionyrelates.,particularly to the means provided fior, adjusting one or more of', the ,cutters 20. aziallyfof the cutter v-liead For k this purpose" I provide for each suchk Vcuttferfa slide21 (Fig. 5)l having aNslot 22A therein.; This slot permits the two portions.

lvide recesses 13 between cutter-supporting i are provided fin theyhead Y 'Y and 1n thek ring in :each cutter-supporting clamp a cutter-2O l.between guideways 23. .Y

1 The' sus@ 21 is also" provided with af dove tailed extension 25 itting a guide-way 25 extending through .the head 1() and ring 11.

A rectangularl recess 26 is formed in the slide and is adapted to receive a rectangular clampingsleeve formedl i'n-two portions 27 Y and 28 (Figo).

These sleeve portions arebevelled attheir adiacentends, as indicated in Fig; 6, and the Vportion 28 is lthreaded at 29 to Vreceive a Y Vclamping bolt 130 which yextends freely through a recess 31 in thesleeve portion 27. Vhen the bolt 30 is tightened, the bevelled sleeve portions 27 and 28 are drawn towards each other. The opening 31 is yof sufficient diameter to permit the v-sleeve portions to be moved slightly out.v of alignment with eachv other, when forced together. Such movement presses the two parts of 'the slide extension miV 25 outward in its guide-way 25, thus claiup ing the slide firmly therein and preventing;r further axial movement thereot'.

A notch or recess 2:32 (Fig. 3) is formed in a portion ot the slide .21 and receives a flange il?) ou an adjusting screw 34 threaded into the head l0. iVheu the clamping holt 2l() is loosened, the slide may he adjusted axially hy turning,r the screw -l-it. Then the slide is in its desired position. it may he held trom displacement by tightening the holt 30 in the clampingr sleeve.

The cutter 20 shown in Fig. .2 is ot the type used 'tor cutting the tongues and the cutter l5 shown in Fig. 8 is oit' the type used `tor culture)I the `grooves.

l'aring4 descrihed the construction and operation of my improved molding cutter, the advantages thereof will he readily apparent. It to' any reason it is desirable to decrease the width oit the tongue or increase the width ot the groove, the slide 2l. may he adjusted axially to throw one ot the cutters out ot alignu'ient with the other cutters in the set. Quick and accurate adjustment of the cutters is thus provided Jfor and it is a very simple matter to so adjust the cutters that the tongues and grooves will tit accuatcly together.

Having thus described my invention and the advantages thereof', I do not wish to he limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim iszl. A molding cutter comprising a head, a plurality ot cutters mounted thereon, and means to adjust one of said cutters axially ot said head. said means comprising a guideway in the head, a slide movable in said guideway, means to clamp a cutter in said slide, and means adjacent said guideivay and enactingr with the head, to secure said slide in adjusted axial position in said head.

2. A molding cutter comprising a head, a plurality of cutters mounted thereon, and means nto `adjust one of said cutters axially ot said head, said means comprising a slide, means to secure said cutter in said slide, a clanipingl sleeve formed in two parts having,r their adjacent ends eppositcly hevelled, and means to draw said sleeve parte together to hind said slide in said head.

3. A molding cutter coniprisincA a. head, a plurality ot cutters mounted thereon, and. means to adjust one ol said critters axially of said head, .said means compris-ing,` a slide axially movalile in a ,cuide-way in said head and having a recess therein, a claiupingr sleeve tit-tingin said recess and formed in oppositely herelled parts, and means lo draw said sleeve parts together against, the walls oit said recess and therehy torce opposite portions ot said slide against the sides ot said guide-way to secure said slide in said head.

Ll. A molding' cutter comprising a head. a plurality ot cutters mounted for' tangential. adjustn'ient in said head, and means to adjust one ot' lsaid cutters axially, said means comprising a channel in the head, a slide movahle iu said channel, means to clamp a. cutter iu said. slide aud to permit tangential adjuslimnt thereof, means to adjust said slid? axiallyI ot said head, and means coacting with the head to clamp said slide in said guide.

A molding cutter comprising a head. a plurality ot cutters mounted tor tangential :uiljustment in said head, and means independent. ot the remaining` cutters, to adjust one ot said cutters axially, said means coniprisinn a channel through said head, a slide guided therein, means to clamp a cutter in said slide,said slide having a notch therein, an adjustingl screw threaded in said head and having a liange litting said notch, and means to positively clamp said slide in axially ad justed position in said head.

In testimony whereof Ihave hereunto aitlined my signature.
